Zappa is pretty happy about h4, which it thinks wins a pawn.  If I go down its
line (after 7. Kxh4), it thinks

1... Rf2-a2 2. Bc4-b5 Ke5-f4 3. Kh4-h5 Kf4-e3 4. Bb5-c6 f5-f4 5. Kh5-g4 Ra2-a1
6. b3-b4 f4-f3 7. Bc6xf3 Ra1-g1 8. Kg4-f5 Ke3xf3 9. a4-a5 Rg1-b1 10. a5-a6
Rb1xb4 11. Kf5-e6 Rb4-a4
 = (5.44)	Depth: 20/32	00:01:01.85	134874kN (2180 KN/s, 2009 splits, 142 aborts)

So I think the Zappa at least handles this position just fine with Black.
